Lette/re Patent No. 101,552, dated April 5, '1870.

IMPROVEMENT IN COUNTER-KNIFE.

The Schedule referred tp in these Letters Patent and making part o! the same.

To all ywhom. it may concern.

Be it known that I, J OHN Tenn, of the city of Reading, county et Berks and State of Pennsylvania, do represent that I have invented certain Improvements on an invent-ion called the Magic Counter-Knife, upon which invention Letters Patent of the United States were granted to one George W'. Griswold about eighteen years ago; and I do hereby declare that the following is a full andexact description of my improvements upon the same, which descn'ption may be bettex: understood by pmsning the references hy the let-v ters A B O t'o the accompanying drawing'.

My improvements are as follows: v

First, a steel spring'on the side of the shuttle, designed to lfacilitate the adjustment of the knife.

Second, a small wheel at the lower end of the knife, for the purpose of 1emleringtl1e motion ofthe knife easier.

Third, 'a metallic lining in the groove in which the knife moves, and uponA which the wheel specified as improvement works with more ease and convenience than upon'the bare wood of the groove.

Said invention, with the improvements, is designed to take the place of both the .yard-stick and the scissors.

The design, as a. whole, is calculated to be used as a. yard-stick, having the gradation of the .yard marked i thereon.

After the material is measured, by placing the'instrnment at right angles with the same, and inserting the material between the bed-piece and the lid of -the instrument, and drawing it back the full length of the design, then placing the left hand on the rear of the shuttle, and the right hand upon the shuttle, pressing thereon, and moving the samer rapidly forward, any materialy or goods can be out perfectly straight without labor or injury to the fingers, and with as much rapidity as the arm can be moved forward, far surpassing the utility' of the scissors for the same purpose.

"hat I claim, and desire to secure by-Letters Patent, is-

In combination with a yard-stick, the steel spring A, wheel B, and metallic lining C, arranged as described.
